Windows Media Player - does high cpu/low gpu always mean cpu bottleneck?

I have another thread regarding a problem I'm having playing 4k on my vizio 50" tv using:

G860 (dual 3ghz)
HD 7850 (2gb ddr5)
4gb ram

When I'm playing the video plays both cores are pegged and system memory stays down around 2gb. The gpu load has a few spikes but the VAST majority of the time it runs under 5%.

I've tried disabling html5 player in youtube and played in Chrome, IE & FF as well as downloading a video file and playing it. Same jumpy/jittery/torn video. I also have the latest drivers.

Thanks in advance!

Sure sounds like it. Full disclosure, I haven't played with 4K yet. From what I know the 7850 shouldn't have any issues playing 4K video. It can't handle 4K games, but a 4K video should be very doable. If it's sitting around at 5% and your CPU cores at pegged at 90%+, then you need a faster CPU. I haven't seen any CPU 4K benches so I'm not sure what you need.

P4s ran at 3.0GHz, 3.2GHz, 3.73GHz, that doesn't make them faster. Your current CPU at 2.0GHz would crush all of them. An i3 (2C/4T) would probably do it. But as I said I haven't seen any benchmarks on this. Mostly because I haven't moved to 4k so I haven't looked.
